Over these she wore a red chrysanthemum pattern uchiki (long jacket) and held a fan in her hand. And after the ceremony she changed into a beautiful pink silk ceremonial kimono....... http://www.hellomagazine.com/royalty...princess-aiko/

A very interesting video in which you can see the rehearsal of "Chakko-no-Gi" ceremony of Princess Aiko. You can also see the ceremonies held for Princess Sayako and Prince Naruhito. You can also see Aiko watching sumo for the first time in September this year. The emperor and the empress and other members of the royal family had dinner together in the Prince's residence in the evening of the ceremony.

Aiko is so adorable on that dresses. she's one of the prettiest little Princess. I also love to see her parents together. They looked so proud of Aiko. And for CP Masako, she seems very happy. I hope she'll get better and better each day.

ever since an heir was born into the imperial family. . . crown princess masako has become more and more happier. . . which is good as we all can see her beautiful smile more often. i just love her smile. . .

Mako and Kako already had theirs when they were about 5 years old respectively. Maybe you were referring to the video that wlee posted - and Mako and Kako's chakko-no-gi ceremonies weren't included?

Japanese princess turn 5 with future in the balance
Japan's Princess Aiko celebrated her fifth birthday on Friday with few clues as to whether the future will see her ascending the Chrysanthemum Throne or bargain-hunting at the local supermarket.
The September birth of her cousin Prince Hisahito, the imperial household's first male heir in more than 40 years, effectively halted progress on a planned change in the law to allow women to take the throne.
But many commentators say the law should still be revised to avert a future succession crisis.
"The birth of Prince Hisahito did not fully solve the heir problem," said Kenneth Ruoff, a professor at Portland State University and author of "The People's Emperor", a study of the modern-day Japanese monarchy.
